The center sheet 29 is provided with flat margins 34 at each side and these marginsaarc overlapped by the inner edges ol the side sheets 3U-3U which are secured to the tiat margins Ill by two lines of rivets lift--36 on opposite sides of the corrugations 33 of the side sheets. The outer vertical edges of the side sheets 30 30 are preferably formed with angular flanges 37 which are attached to the corner posts 25 by bolts 38. The upper edges of the. sheets are suitably secured to the car franr ing as by bolts 39 which extend through the end plate 26. The lower edges of the sheets are preferably formed with inturned flanges 39 which are secured to the end sill by bolts ill. the flanges intervening between the end sill QT and the flooring 28 so as to make a grain-proof connection The corrugations, besides serving to stifi'en and reinforce the structure against cargo thrusts, also act as load carrying members and take some of the roof load. For this reason, it is desirable that the center sheet be made heavier than the side sheets and the corrugations adjacent; the center of the panel be heavier than those at the side. It will also be obvious that by extending the flat margins of the center sheet back of the corrugations 32") so as to provide box girders at points intermediate the vertical center line of the end and the sides of the car, provide additional reinforcements for the portions of the panel provided with the shallow corrugations. Assuming that the end ladders l1 project as far out as the law allows, with corrugations 33 formed as shown. it will be obvious that were the corrugations all of the same depth it would be necessary either to sacrifice the additional strength and rigidty at the center of the car by making all of the corrugations relatively shallow or. it they were all deep, to set the end farther back with respect to the car. which would be at the sacrifice of the inside" longitudinal dimension. The diflicult v is resolved by making the center corrugation as deep as feasible and have the corrugations on opposite sides thereof dc crest. in depth toward the sides of the car. Forming certain of the shallower corrugations on separate sheets facilitates the opera tion of pressing the sheets since shallow corrugations are much more easily made than those of greater depth.

I claim:

1. A sheet metal end structure for a railway car, comprising a plurality of sheets overlapped and secured together and to the frame of the car, and formed with one single corrugation of maximum depth adjacent the vertical center line of the end and with shallower corrugations on either side of the same, the sheet having the said deep corrugation being thicker than. the other sheets.

2. A sheet metal end structure for a rail way car comprising a plurality of sheets overlapped on vertical lines and secured to gether and to the frame of the car, and formed with one single corrugation of maximum depth adjacent the vertical center line of the end and with shallower corrugations on. either side of the same, the sheet having the said deep corrugation being thicker than the other sheets.

3. A sheet metal end structure for a railway car Ct; uprising metal sheets formed at the center of thc end with a single corrugation of maximum depth and with a plurality of parallel vertically disposed corrugations becoming gradually shallower toward the opposite sides of the panel.

l. A sheet metal end structure for a railway car' comprising a plurality of metal sheets joined together along vertical lines and provided with a plurality of vertical corrugations. which are deepest at the central portion of the end and decrease in depth toward the the sheet at the center of the structure being provided with fiat marginal portions which overlap one of the corrugations of the adjacent sheets providing a box girder extending substantially from the floor of the car to the roof thereof.

5. A sheet metal end structure for a. railway car comprising a plurality of metal sheets joined together along vertical lines and provided with vertical corrugations, the sheets at the center of the structure being of thicker material than the adjacent sheets, and provided with inar m'nal portions which overlap one of the corrugations of the said adjacent sheets.

(3. sheet metal end structure for a railway car comprising a plurality of metal sheets formed with relatively deep vertical corrugations adjacent the center vertical line of the end and with shallower vertical corrugations at the. side thereof, the sheet at the center of the structure being provided with marginal portions which overlap one of tho corrugations of the adjacent sheets.

7. A sheet metal end structure for a railway car comprising a plurality of metal sheets formed with relatively deep vertical corrugations adjacent the center vertical line of the end and with shallower vertical corrugations at the side thereof, the sheet at the center of the structure being provided with marginal portions which overlap one of the corrugations of the adjacent sheets, the side sheets of said structure being provided with attaching flanges adapted to be secured to the side wall of the car.
